Adjustable Pitch Awning Arm Mechanism for Water Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing awning assemblies lack flexibility in deployment and retraction mechanisms, particularly for movable structures like recreational vehicles, as they do not allow for adjustable angles and positions to accommodate varying weather conditions and user preferences.
Innovation Solution
The awning assembly incorporates adjustable pitch arm assemblies that can be manually adjusted between extended and collapsed positions, allowing the canopy to be moved from a deployed position to tilted or retracted positions, with a canopy rod supported by arm assemblies that include a roller assembly for easy extension and retraction, and a lock mechanism to secure positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the awning assembly uses fixed arm assemblies, then the structure is simple and stable, but the awning cannot be adjusted to different angles and positions to accommodate varying weather conditions and user preferences
Solution Approach 1:
The arm assembly is divided into multiple segments that can be independently adjusted. The first and second arm assemblies each include adjustable pitch mechanisms that allow independent control of canopy angle, enabling the awning to be segmented into adjustable sections for versatile positioning.
Solution Approach 2:
The arm assemblies transition from fixed to dynamically adjustable structures. The pitch adjustment mechanisms allow the arms to change their angular position dynamically, enabling the awning to adapt to different weather conditions and user preferences while maintaining structural integrity.
2Ease of operation
If the awning assembly includes adjustable pitch arm assemblies, then the awning can be positioned at different angles for water drainage and user comfort, but the mechanism for manual adjustment becomes more complex
Solution Approach 1:
The pitch adjustment mechanism is designed to be manually operable without requiring external tools or complex machinery. The mechanism allows users to easily adjust the canopy pitch angle through simple manual operations, making the system self-sufficient for positioning adjustments.
3Productivity
If the roller assembly is designed for easy extension and retraction, then the awning can be quickly deployed and stored, but the structural strength may be compromised
Solution Approach 1:
The roller assembly is pre-configured with mechanical advantages that allow quick deployment without compromising strength. The assembly includes pre-positioned support structures and locking mechanisms that ensure structural integrity is maintained during rapid extension and retraction operations.

AI summary
An awning assembly includes a canopy, a first and second arm assembly, and a canopy rod. The arm assemblies can each include an adjustable pitch arm assembly configured to adjust the pitch of the canopy. The canopy rod has a first end and a second end each supported by one of the arm assemblies. Manual adjustment of the adjustable pitch arm assemblies is configured to move the ends of the canopy rod. The canopy is movable from a first deployed position to a second deployed position when the adjustable pitch arm assemblies are both manually adjusted from an extended position to a collapsed position. The canopy can be movable from either deployed position to a retracted position without manually adjusting the adjustable pitch arm assemblies. The adjustable pitch arm assemblies can change positions in response to water being collected on the awning assembly to drain the collected water.
